FWIW: we use STP, and use a couple of HMCs as the NTP source for STP, with the HMC servers themselves getting time from our stratum 1 NTP servers which use a GPS receiver for the time. That makes the HMC stratum 2. And if z/OS was then serving the time via NTP, I believe z/OS would be considered stratum 3. But I see little point in that: there's more stratum 2 servers distributed around our network.
Of course one may reasonably argue that STP could/should point directly to the stratum 1 NTP server. Which is probably a fair point. But I tend to be biased against making my mainframe configuration directly dependent on something I don't have direct control over. That's just one of my little quirks...
